For new objects, using S3 events and Lambda functions is great for converting file types, creating thumbnails, performing data scans, and carrying out other operations.
Understanding distribution metrics Custom metrics submitted from Lambda functions are aggregated as distributions, because they are designed to instrument applications, independent of the underlying hosts.
You can use new or existing AWS Lambda functions to process your data such as filtering, masking, redacting, compressing, changing the format, or modifying objects for your specific applications.
